- --WW Check disks, but do not write changes.
-
- --ff Don't check disks (fastboot).
-
- --vv Have both ffssmmoouunntt and ffsscchheecckk output verbose
- information while running (the default).
-
- --nn Don't attach disks or export prefixes.
-
- --pp Print out actions but don't execute them.
-
- --hheellpp Print a summary of the command-line options
- and exit.
-
- --dd _d_e_v_i_c_e_D_i_r_e_c_t_o_r_y
- Specifies the directory containing the device
- files. The default is "/dev/".
-
- --ii _s_p_r_i_t_e_I_D Causes prefixes that this machine will export
- to be preloaded into the prefix table with
- _s_p_r_i_t_e_I_D as the server. This prevents the
- machine from broadcasting for its own pre-
- fixes while the disks are being checked.
-
- --ffsscchheecckk _f_s_c_h_e_c_k_P_r_o_g
- Use this to specify an alternative fscheck
- program, i.e., when testing a new fscheck.
-
- --cc Conditionally check the disks. If the disks
- were just checked by _f_s_c_h_e_c_k and we are now
- rebooting, then we don't have to check again.
- If the --cc flag is present then the disks
- won't be rechecked.

- FFssmmoouunntt is used during system boot to check the disks for
- inconsistencies and to export prefixes. It is a replacement
- for ffssaattttaacchh, and is intented to be used without a mount
- table. It uses ffssiinnffoo to determine what filesystems are on
- the disks connected to the host, ffsscchheecckk to check the
- filesystems found (if they are OFS), and pprreeffiixx to mount and
- export them. In this way, disks can change hosts, change

- prefixes, or change parititioning without having to update a
- mount table file.
-
- FFssmmoouunntt does some checking before it pprreeffiixxes filesystems.
- If it finds filesystems whose cylinder extents overlap, it
- will only pprreeffiixx the larger of the filesystems. If more
- than one filesystem has the same prefix, it will try to
- mount those filesystems until one successfully mounts and it
- will ignore the remainder. If a filesystem has a prefix of
- a filesystem already in the prefix table, it is ignored.
-
- Currently, ffssmmoouunntt detects and notes root partitions, but
- does not try to either check or mount them.
-
- Upon completion, ffssmmoouunntt creates a ffssmmoouunntteedd file in
- //hhoossttss//$$HHOOSSTT//ffssmmoouunntteedd reporting the filesystems it mounted
- and exported, and when it did so.

- FFssmmoouunntt returns the same error codes as ffssaattttaacchh:
-
- 0 No error.
-
- 1 An error was found in the root partition. Reboot the
- system. See ffsscchheecckk for details.
-
- 2 A hard error occurred. There was some problem in either
- ffssaattttaacchh, ffsscchheecckk, or pprreeffiixx that prevented ffssaattttaacchh
- from completing normally.
-
- 3 FFsscchheecckk returned a soft error indication. See ffsscchheecckk
- for details.
-
- 4 An error was found in the root partition, but the
- number of consecutive times that ffsscchheecckk was run and an
- error found exceeds the limit.
